2 Claims. 1

This invention relates to new and useful improvements in windowconstructions and more particularly to revolving windows of the typeused for ventilating homes, buildings, factories and the like wherescreens and storm sashes are not employed.

The primary object of the present invention is to provide a windowstructure including a swingable sash mounted in a casing and embodyingnovel and improved weather stripping means between the sash and thecasing.

Another important object of the present invention is to provide arevolving sash of the aforementioned character in which the weatherstripping means also functions as a means for preventing swingingmovement of the sash relative to the casing when it is desired to retainthe sash in its closed position.

A further object of the present invention is to provide a revolvingwindow including a swingable sash, a casing for the sash, slidableweather strips carried by the casing for engaging the sash, and amanually operated means for retaining the strips out of engagement withthe sash whereby the latter may swing, in an unrestricted arc, foropening thereof.

A still further aim of the present invention is to provide a revolvingwindow that is simple and practical in construction, convenient toservice and install, small and compact in structure, quickly and readilyadjusted for opening and closing the sash forming part thereof, neat andpleasing in appearance, relatively inexpensive to manufacture. andotherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure l is a front elevational view of a window constructed inaccordance with the present invention, and showing the upper and lowersash thereof in their closed position;

Figure 2 is an enlarged horizontal sectional view taken substantially onthe plane of section line 2-2 of Figure l; y 1

Figure 3 is a view similar to Figure 2 but showing the lower sashpartially open;

Figure 4 is a vertical sectional view taken substantially on the planeof section line 4-4 of Figure 2;

Figure 5 is an enlarged vertical sectional view taken substantially onthe plane of section line 5-5 of Figure 1 and showing the weather stripdisposed out of the recess in the lower rail of the lower sash;

Figure 6 is a view similar to Figure 5 but showing the weather strip inthe recess in the lower rail of the lower sash;

Figure '7 is an enlarged, fragmentary, front elevational view of thepresent window structure to illustrate the manner in which the weatherstrips are locked out of engagement with the sash;

Figure 8 is a horizontal sectional view taken substantially on the planeof section line 6-8 of Figure '7; and

Figure 9 is a vertical sectional view taken substantially on the planeof section line 9-9 of Figure 8.

Referring now to the drawings in detail, wherein, for the purpose ofillustration, there is disclosed a preferred embodiment of the presentinvention, the numeral [0 represents the instant revolving windowstructure generally, including an upper sash l2, 9. lower sash M, anupper casing It for the upper sash l2, and a lower casing It! for thelower sash.

It is preferred thatthe casings I6, l8 and the sashes I2, I 4 beconstructed of suitable light weight, durable non-corrosive metal.However, any suitable material may be used depending upon the cost ofinstallation for a particular job, the availability of material and thecost of manufacture, as well as the type of building structureassociated therewith.

Since the casings l6, l8 are similar in construction and, further, sincethe sashes l2, H are also similar in construction, a description for onecasing and one sash will suiiice for both. Furthermore, it is understoodthat a single sash and easing, or any suitable number of sashes andcasings may be employed, depending upon the size of window opening,light and ventilation required or desired.

The sashes l2 and I 4 are substantially rec-, tangular in configurationand each is composed of an upper rail 20, a lower rail 22, and siderails, 24 and 26. The rails 20, 22, 24, and 26 are joined in anysuitable manner, or form an integral struc-,

ture, and support a panel 28 of translucent or transparent material,such as glass.

The casings l6 and I8 are also substantially rectangular in shape andeach includes an upper portion 30, a lower portion 32 and side portions34 and 36. The inner face of the side portion 36 is formed with alongitudinal groove 36 for receiving a tongue or extension 40 on theside rail 26 and the forward face of the side portion 34 is providedwith a longitudinal groove 42 for receiving a tongue or extension 44 onthe side rail 24 in order to seal the side rails of the sashes to theside portions of the casings when the sashes are in their closedposition.

Projecting laterally from the central portions of the upper and lowerrails l2 and H are pivot pins or trunnions 46 that enter suitablerecesses or depressions 48 provided in the inner and lower portions ofthe casings for individual horizontal swinging movement of the sashesrelative to the casings. The pins 48 are secured to the sashes in anysuitable manner so that they may be removed from the inside of thewindow structure It to facilitate a replacement or repair of parts.

The upper and lower portions 30 and 32 of the casings are formed withlongitudinally extending grooves or channels 50 that slidably receivecombined weather strips and retainer strips 52. The strips 52 areconstructed of any suitable material and are provided with openings 54adjacent their ends that receive bolts 56. The heads 58 of the bolts 56are preferably square and are slidably received in intersecting verticaland horizontal grooves 60 and 62 formed in the walls defining thegrooves 50, to hold the bolts against rotation relative to the strips52.

The bolts 56 are also slidably received in intersecting vertical andhorizontal grooves or slots 64 and 66 provided in the upper and lowerportions of the casings. The threaded ends of the bolts 56 receivecombined lock nuts and finger grips 68 and the inside surfaces of theportions 30, 32 are formed with recesses in which the combined lock nutsand finger grips 68 are positioned to obviate any harmful projections orobstructions.

A pair of substantially U-shaped spring members 12 are secured in eachof the grooves 50 and yieldingly urge the strips 52 into grooves 14provided in the rails and 22.

In practical use of the present invention, when the sashes are in theirclosed position, the strips 52 are received in the recesses or grooves14, as shown in Figure 6, to hold the sashes against opening and toprevent the passage of water between the sashes and their casings.

To open the sashes, it is merely necessary to move the bolts 56vertically in the slots 64 and horizontally across the slots 66,whereupon the strips 52 will be moved out of the recesses H, as shown inFigure 5.

In view of the foregoing description taken in conjunction with theaccompanying drawings, it is believed that a clear understanding of thedevice will be quite apparent to those skilled in this art. A moredetailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention, the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and within the scope of the appendedclaims.

Having described the invention, what is claimed as new is:
